Spindle epithelial tumor with thymus-like differentiation of the thyroid in a 70-year-old man

Spindle epithelial tumor with thymus-like differentiation (SETTLE) is a very rare tumor of the thyroid gland mostly occurring in young patients. The imaging findings of SETTLE tumors are yet to be defined. However, they are usually described as well-defined heterogeneously enhanced masses on CT scan. The current case has the potential growth as compared with a 2009 chest radiography. We took into account the possibility of SETTLE in the case of a bulky mass in patients over 70 years old, particularly in the lower neck. Herein, we report a case of the oldest patient so far. The patient underwent a right lobectomy of the thyroid and mass excision. Follow-up CT scans after 6 months revealed no local recurrence. Surgery is the gold standard treatment for SETTLE. Chemotherapy and radiotherapy could be another possible option for patients with advanced stage SETTLE.

An Adenocarcinoma of Lung with Unusual Very Slow Growth : A case report

The prognosis of lung cancer is very poor. Patients with lung cancer have usually no symptom in early stage or some mild cough, sputum. When patient feel weight loss or dyspnea, majority of patients with lung cancer are advanced stage and inoperable. The growth rate of lung cancer is different according to cell type of tumor and related to prognosis. Generally, tumor. doubling time (TDT) of lung cancer has been known that small cell lung cancer is about 65 days, squamous cell carcinoma is about 90 days, and adenocarcinoma is about 185 days. There has been rarely reported of lung cancer with very fast or very slow growth. The prognosis of a slow growing lung cancer is relatively good but rapidly growing cancer is not. We report a very rare case that surgicallytreated early stage non-small cell lung cancer (adenocarcinoma) with 4-year- TDT without invasion or distant metastasis
